So did DOJ really pay $16 for muffins? Of course not. In fact, it's obvious that someone quite carefully calculated the amount they were allowed to spend and then gave the hotel a budget. The hotel agreed, but for some reason decided to divide up the charges into just a few categories instead of writing a detailed invoice for every single piece of food they provided. This is unremarkable. In fact, I'm here to tell you that this happens All. The. Time. I've been involved in what feels like a thousand conferences of this kind, and I'd be shocked if it happened any other way. Hell, I'm surprised DOJ even got that much of a breakdown. Far more commonly, your event person negotiates what kind of refreshments you'll get, and the invoice ends up looking something like this:

Refreshment table (bev/morn/aft) — 5 days....................$39,500

None of this is to say that DOJ didn't overspend on its conferences. In fact, it sounds like they did — though in some cases this was just an artifact of applying overhead costs to the food instead of accounting for it separately. But the $16 muffin? That's a myth. It'll never die now that it's been delivered to posterity thanks to some enthusiast in the OIG who broke out a calculator and mistakenly assumed they could calculate actual costs this way, but it's still a myth.
